OPERATING INSTRUCTIONS
Thank you for purchasing the MTH Electric Trains GP38-2 diesel
locomotive. This ¼” scale reproduction of the famous GP38-2 locomotive
measures over 15” in length and weighs almost 5 pounds. Despite its scale
size, the locomotive is capable of operating on O-31 3-rail track with any
compatible AC transformer, (see page 33 for a complete list of compatible
transformers and wiring instructions) and is completely compatible with
most other 3-rail locomotives, rolling stock and accessories.
The locomotive is equipped with several deluxe features that are simple
and fun to operate. Each feature is described among the following pages
which should be read before the engine is operated. For those of you who
can’t wait to get started, the Quick Start Operating Instructions, found on
page 3, should be read so that you understand the basics of the operating
system.

QUICK START - BASIC OPERATION
The MTH GP38-2 contains state-of-the art electronics with several built-in
automatic features for incredibly realistic operation. Despite these advanced
features, the GP38-2 is easy to operate with any compatible standard AC
transformer (see the compatibility chart on page 33).
The GP38-2 model is controlled by a ProtoSound® DCRU® electronic
reverse unit. The reverse unit operates in the same manner that all reverse
units function by using forward, neutral and reverse states that are entered
each time the throttle is turned on and off or by using the transformer
direction switch (if so equipped).
The reverse unit is designed to ignore
dirty track, dead spots on switches or
minor short circuits without disrupting
the engine operation, even at slow,
prototypical speeds. Once the engine is
placed on the track, the transformer
throttle can be advanced. You will see
that only the engine’s lights come on and
two dings from the sound system will
chime followed by the air compressor
pump sounds. The engine does not run.
This is known as the RESET state and is
explained in more detail beginning on
Page 5. The ProtoSound® DCRU®
will not power the motor until the
throttle is turned OFF and then ON
again. At this point, the engine will
now function just like any other
electronic or mechanical E-unit.

PROTOSOUND® DCRU® REVERSE UNIT
As mentioned in the Basic Operating section, the engine is controlled by a
DCRU® reverse unit that contains the standard forward-neutral-reverse
states found on most reverse units. However, as described earlier, when
power is first applied to the track, the reverse unit begins in RESET or what
seems like a neutral state. Power must be interrupted again to get the
locomotive to enter the forward state. It is this first RESET state that gives
ProtoSound® its unique, remote controlled functions. The system will enter
RESET whenever power to the track is off for three or more seconds.
NEUTRAL will be referred to as the state between Forward and Reverse.
ProtoSounds® is equipped with a microprocessor, that, depending on the
amount of memory it is allotted, allows the user to utilize several remotely
activated functions. In the simplest terms, ProtoSounds® has its own
“Computer" controlling these functions. In fact, the power of this
microprocessor is the same as that of a 286 desktop computer! In order to
access many of these remotely controlled functions, the user must be in the
RESET state to do so. RESET is entered anytime power to the locomotive
has been off for more than 3 to 5 seconds. When the engine first enters
RESET, the microprocessor initiates a system check to determine if the
system, transformer and engine are operating correctly. This takes
approximately 2.2 seconds during which you will hear the engine’s startup
sounds begin. In order for ProtoSounds® to properly initiate the system
check, do not advance the transformer throttle past 10 volts when you first
5
MTH GP38-2 Diesel Operating Manual
PREMIER LINE
enter RESET, wait for the diesel startup sounds to begin and then slowly
turn the transformer throttle to the off position and then back on again to
enter the forward phase. Interrupting the power too quickly may cause the
system to re-enter RESET (signaled by two dings of the bell). Should this
happen, wait longer before interrupting the power to enter the Forward
phase.
ProtoSounds® comes with several programmable functions, including
remote Diesel Engine Volume Adjustment, Separate Bell Button Operation
(pre-programmed at the factory), Horn In Neutral Operation,
ProtoCoupler™ On/Off Control, Squeaking Brakes and Passenger Station
or Freight Yard Proto-Effects. Each of these features are described in more
detail later. You will notice that when in RESET, your engine will not
respond to the whistle button with a horn blast or continuous bell ringing.
In fact, when in RESET and the whistle button is depressed, only one single
bell chime will be heard each time the whistle button is pressed. If you
don’t want to configure or change your locomotive using any of these
programmable features, simply leave RESET and wait 2.2 seconds before
interrupting the power to put the engine in forward. After you leave
RESET, your engine will operate normally in all the direction states of
forward, neutral and reverse. Remember though, once power is turned off
for more than 3 seconds, the next time power is applied to the track, your
engine will be back in RESET.
HORN OPERATION
Your GP38-2 ProtoSound®-equipped engine is equipped with a digital
recording of a diesel horn. The horn sound can be activated anytime the
engine is in forward or reverse by pressing the whistle button on your
transformer. The horn will continue to blow as long as the whistle button is
depressed. The horn will not function in RESET and must be configured
through a RESET option to allow the whistle to work when the engine is in
neutral. See page 20 for information on horn programming in the Using
RESET To Program ProtoSounds® section of this manual.
BELL OPERATION
Your GP38-2 ProtoSound®-equipped engine is equipped with a digital
recording of an actual diesel engine bell. The bell can be turned on or off
with any separate bell button, like the Lionel® Railsounds® No. 5906 Bell
Button, by simply pushing the button. If you don’t have a separate bell
6
MTH GP38-2 Diesel Operating Manual
PREMIER LINE
button, the bell can be controlled through your transformer’s whistle button
whenever the engine is in NEUTRAL. The bell will never ring
continuously in RESET (Remember NEUTRAL is the state between
Forward and Reverse). Once the bell is turned on, it will continue to ring
when the engine is cycled into forward or reverse until you press the bell
button or re-enter NEUTRAL and turn the bell off with the whistle button.
In fact, because of ProtoSounds® state-of-the-art design, the
microprocessor remembers its last command. Therefore, unless you turn
the bell off before you quit running your train, the next time you run the
engine, the bell will come on. No matter whether you come back an hour
later or a year later, the bell will begin chiming once the engine enters one
of the three directional states.
To turn the bell on using the transformer’s whistle button, turn on power to
the track and cycle the engine into NEUTRAL. Turn the throttle to 8 volts
or less (any higher voltage will arm the ProtoCoupler™) and press the
whistle button. The bell should begin chiming. To turn the bell off, press
the whistle button again. If you want to keep the bell on while running the
engine, simply interrupt the power with the transformer throttle or the
transformer directional switch and enter forward or reverse.
PROTO-COUPLER™ OPERATION
Your GP38-2 ProtoSound®-equipped locomotive is equipped with two
coil-wound ProtoCouplers™ for remote uncoupling action. Because the
ProtoCoupler™ is controlled through ProtoSounds® microprocessor, it
doesn’t require an uncoupling track section or modification to your layout
to function. The three simple steps below are required to operate the
coupler.
1. Put your engine in NEUTRAL and turn the throttle all the way up.
2. Press the transformer
whistle button to “Arm"
the coupler. (You will
hear a “Clank").
3. After arming the
coupler, press the whistle
button again to open the
coupler.

When the knuckle fires open you will hear the buzzing of the coil
energizing and the sound of the air lines coming apart. It can best be
described as a CHA-CHUSHHH sound. The coupler doesn’t have to be
fired in NEUTRAL. Once the
coupler is armed it can be fired
in Forward, Neutral or Reverse.
However, you may find that the
coupler doesn’t open when
firing the coupler at high
speeds. Reduce the voltage
setting on your transformer if
this occurs and run your engine
at a slower speed before firing
the coupler. If the coupler
continues to open erratically, try lubricating the knuckle with light oil as
indicated in Fig. 3.
For multiple heading purposes, only one of the two ProtoCouplers™ will
function at any one time. Use the coupler direction switch as shown in
Figure 1 on page 3 to select either the front or rear coupler. Simply slide
the switch toward the direction of the coupler you want to make active.
NEUTRAL-ACTIVATED CAB CHATTER SOUNDS
Your engine is equipped with four dispatacher-to-engineer “Cab Chatter”
radio transmissions that occur every 2 to 30 seconds. Each sequence will
play at random intervals to eliminate repetition. While the sounds are
selected to play randomly by the microprocessor, there is no guarantee that
you won’t hear the same message repeated twice or more times.
SQUEAKING BRAKE SOUNDS
ProtoSound® equipped engines feature the ability to play the sound of
squeaking brakes whenever your engine slows in speed. There are two
settings for activating the squeaking brake sounds. The default setting
allows the brake sounds to play
while the engine is in forward or
reverse and the transformer
throttle is lowered from a high
setting to a low setting (14 volts
to 8 volts or less). The second

setting requires that a bell button be used to “arm” the brake feature and is
explained in more detail in the “Activating Freight Yard Sounds” section
found later in this manual. The sound itself is a stored record on the
ProtoSounds® software chip and will always play the same brake sound for
the same three second length each time the voltage is reduced from high to
low. Some practice may be required to synchronize the playing of the brake
sounds with the movement of the engine. It is not uncommon for the engine
to stop before the brake sound is completed. Operators will find that by
coordinating the movement of the throttle setting from 8 volts to off will
allow the engine to maintain its movement while the brake sounds play.
Note: The brake sounds will not be heard if the transformer throttle is not
set above 14 volts and/or not reduced below 8 volts.
TIPS ON USING THE SQUEAKING BRAKE FEATURE
Note: Consistent activation of the wheel
flange squealing is determined by the condition of your transformer’s whistle
button rectifier disc.

FREIGHT YARD SOUNDS (FYS)
ProtoSounds® comes equipped with operator controlled Freight Yard
Sounds, hereby referred to as FYS. This easy to use feature plays digitally
reproduced freight yard sounds whenever your engine stops on your layout
and is parked in the Neutral position. No additional wires or modifications
are needed on your layout to enjoy these amazing sound effects. The
sounds themselves are randomly generated and randomly “shuffled” on the
ProtoSounds® software chip. This gives the system the ability to produce
different sounds in a different order each time FYS is enabled. These
different sounds are heard each time you cycle the transformer throttle from
ON to OFF in the same manner that you would cycle the throttle to enter the
various states of Forward, Neutral and Reverse. The entire FYS sequence is
designed to simulate the arrival, loading or unloading and departure of a
freight train in a freight yard. Each sequence is described in more detail in
the following sections.
USING FREIGHT YARD SOUNDS
Your ProtoSound® equipped engine features an operator controlled freight
yard sound set. Once activated, this easy-to-use feature plays the sound of
freight yard activitities whenever the operator parks the engine in the
neutral position.
ARMING THE FREIGHT YARD FEATURE
Before FYS can be heard, ProtoSound® must be told to activate the
feature the next time the engine enters the neutral position. This can be
accomplished in one of two ways.
Option 1: If you are using a separate bell button controller to ring your
bell (like the Lionel® Railsounds® number 5906 bell activation button),
you can activate the feature by pressing and holding down the bell button
for three or more
seconds (it doesn’t
matter if you are in
Forward, Neutral or
Reverse). You will
hear the bell chiming

carefully, you should hear an air release sound after three seconds have
passed. At this time you can release the bell button. (Note: because the air
release sound may be difficult to hear, we recommend that you count out a
full three seconds before releasing the bell button.) The bell will continue
to chime, so if you want to turn off the bell ringing, simply press and release
the bell button a second time. If you were in Neutral when you triggered
the brake feature, interrupt the transformer throttle to enter either forward or
reverse and allow the engine to begin moving. (Note: the feature will only
be activated in the first direction state you enter after arming the feature
from the Neutral position. You cannot interrupt the power twice to enter
another direction state and still have the brake feature active.) Once your
engine begins moving, you can trigger the sounds to begin playing
whenever you enter Neutral.
Option 2: If you do not have a separate bell button on your layout, you
can still activate the feature with your transformer whistle button. To
activate the feature, turn on the transformer throttle and get your engine into
the Neutral position (not RESET). Once in Neutral, set the transformer
throttle at 8 volts or less and press and hold the whistle button for at least
three seconds. You will hear the bell chiming begin and if you listen
carefully, you should hear an air release sound after three seconds have
passed. At this time you can release the whistle button. (Note: because the
air release sound may be difficult to hear, we recommend that you count out
a full three seconds before releasing the whistle button.) The bell will
continue to chime, so if you
want to turn off the bell
ringing, simply press and
release the whistle button a
second time. Interrupt the
transformer throttle to enter
either forward or reverse
and allow the engine to
begin moving. (Note: the
feature will only be activated in the first direction state you enter after
arming the feature from the Neutral position. You cannot interrupt the
power twice to enter another direction state and still have the brake feature
active.) Once your engine begins moving, you can trigger the sounds to
begin playing whenever you re-enter Neutral.

ACTIVATING THE FREIGHT YARD SOUNDS
Before FYS can be heard, the feature must be armed as described on the
proceeding pages. Once armed, activating the FYS effects is accomplished
by simply interrupting the transformer throttle and parking the engine in the
Neutral position with track power remaining on. Remember, power to the
track must remain on while the engine sits in Neutral in order for the FYS
effects to operate.
At this point ProtoSounds® has taken over control of your engine and
disabled the bell and whistle buttons from responding to any futher operator
input. In addition, ProtoSounds® has reconfigured the way the reverse unit
functions by disabling the Reverse state during operation of the FYS
effects. This forces the engine to leave your freight yard in the same
direction that it arrived in. The following operator controlled “events”
control FYS’s actions and sound effects.
Event 1 (Forward) While the locomotive is running in forward (or
reverse) FYS is activated by the operator pushing and holding the bell
button down for three or more seconds. The locomotive bell begins
chiming and can be left on or turned off without disabling FYS.
Event 2 (Neural Before Reverse) The operator now interrupts the
transformer throttle to stop the engine and put it into Neutral. If the throttle
setting was at 14 volts or higher , ProtoSounds® will play the sound of
squeaking brake sounds as the engine comes to a halt.
A. Upon stopping of the engine, the operator must immediately turn
the throttle back on to keep the engine in the Neutral position. If the
bell was not turned off after activating
FYS, it now turns off automatically.
Note: Failure to turn the throttle back
on within 3 seconds of leaving the
Forward phase will disable FYS and
shutdown ProtoSounds®. The next time
you turn power back on your engine will
be in the RESET position. See page 5 for more information on
RESET.

B. After entering Neutral, ProtoSounds® will immediately play an
air release sound followed approximately 2 seconds later by a radio
arrival message (cab chatter).
Immediately following the radio arrival
message, the sound of freight car doors
can be heard opening, followed by the
sounds of freight loading and unloading.
At this point various freight yard sounds
can be heard including the
loading/unloading operation, engine
sounds, yardman “slang”, and additional
freight car door sounds.
Event 3: (Reverse) The operator now interrupts the transformer throttle
again to enter the next reverse unit phase; reverse. In an effort to enhance
realism, FYS has disabled the reverse
phase so that it doesn’t power the motors
causing the engine to move backward.
Upon entering reverse, FYS confirms to
the operator that it has entered the reverse
phase by immediately playing a highlight
sound best described as a rumbling sound.
You may have to go through the entire
FYS sequence several times before you can
clearly identify this sound. After the rumbling highlight is played, the
freight yard sounds heard in Event 2 continue to play randomly.
Event 4: (Neutral Before Forward) The operator now interrupts the
transformer throttle again to enter the next reverse unit phase, neutral before
forward. FYS confirms to the operator that it has entered the neutral before
forward phase by emitting two quick air release sounds. This is followed
approximately two seconds later by a radio
departing message and continued freight
yard loading and unloading sounds.

Event 5: (Forward) The operator now interrupts the transformer throttle
again to enter the next reverse unit phase; Forward. FYS confirms to the
operator that it has entered the Forward phase by playing a radio messagne
followed by the freight car door closing. Within 2 seconds of the door
closing, the locomotive bell begins chiming.
After approximately 8 chimes of the bell, the
engine begins moving in the forward phase
with the bell continuing to ring another 8
chimes before automatically turning off.
Once the bell turns off, the operator regains
control of the transformer whistle and bell
buttons and can ring the bell or blow the
whistle as usual.
Note: When entering the Forward phase of FYS, it is important to set the transformer
throttle at a high enough setting that will allow the engine to begin moving once FYS
automatically activates the motors. Otherwise the engine will just sit still until you increase
the transformer throttle setting on the transformer. However, don’t set the throttle setting too
high or the engine will go racing away faster than you might expect.

SELF-RECHARGING BATTERY BACKUP
ProtoSounds® state-of-the-art design includes a self-recharging battery
backup system for improved performance at any speed. The battery ensures
that power to the sound system will remain on during directional changes,
setting RESET options or when travelling over dirty track and switches.
The self-recharging battery backup system is automatically turned on or off
whenever track power is turned on or are off. There are no switches needed
to enjoy the benefits of the automatic battery backup system.
ProtoSounds® contains a warning alarm if the battery backup system fails
to automatically disengage when track power is turned off. Should the
backup system fail, you will hear a repeating whistle blast indicating this
has occurred. Should this happen, unplug the battery from the
ProtoSound® module (to prevent the battery from being run down) and
contact MTH for instructions on returning the tender for repair.
REPLACING THE PROTOSOUND® BATTERY
The ProtoSound® battery (located inside the cab body), is a special NiCad
7-cell, 8.4v battery - NOT the 6-cell, 7.2v battery found in most
convenience stores. The 6-cell NiCad is NOT recommended for use with
ProtoSound® applications. The battery is continually charged from the
track when power is applied and should last for up to five years. In
addition, the NiCad battery is a dry battery and should not leak or cause any
damage to your locomotive during its lifetime.
If you notice that the sounds seem distorted or garbled at low voltages or
become silent when power from the transformer is shut off, the battery may
be going bad. Before replacing the battery, you should put the engine in
NEUTRAL and leave the transformer throttle set at about 12 volts for 15
minutes. This should temporarily recharge the battery. If the garbled or
distorted sounds are reduced, then your battery charge has worn down. You
can give your battery a full charge by leaving the engine ON in the
NEUTRAL position for 18 hours. (Make sure the smoke unit switch is in
the OFF position to prevent harm to the smoke unit wicking).
If you need to replace the battery, replacement ProtoSound® batteries are
available from MTH ProtoSound® Electronics at 7020 Columbia Gateway
Drive, Columbia, MD 21046. A standard 9v alkaline battery can be
16
MTH GP38-2 Diesel Operating Manual
PREMIER LINE
substituted as a temporary fix, but since alkaline batteries can’t take a
charge, it will eventually wear down. Regardless, it should give you a week
to a couple of months use while you wait for your replacement
ProtoSound® battery to arrive.
PROTOSOUND® VOLUME ADJUSTMENT
Your ProtoSound® system has two types of volume adjustment. A
manual turn knob on the bottom of the chassis (See Fig. 4 below) allows
you to control all the sounds in the system and a remote control “RESET"
option (Option # 6), allows you to control the volume level of the engine
sounds remotely from the transformer. Turning the volume adjustment
knob clockwise will increase the volume and counterclockwise will lower
the volume of all sounds; bell, horn, engine sounds, Cab Chatter, etc. For
information on operating the RESET volume adjustment option, see the
section entitled “Programming ProtoSound RESET Options” on the
following pages.

USING “RESET" TO PROGRAM
PROTOSOUNDS®
As mentioned earlier, there are several programmable options in each
ProtoSound®-equipped engine that can be remotely set from any
compatible standard AC transformer equipped with a whistle button. For a
list of compatible transformers, see the chart on page 33. This hands-off
approach gives you unprecedented control of your railroad empire’s motive
power never before seen in model railroading. Each programmable feature
can be accessed whenever your engine is in the RESET state as described
earlier on page 5. By following the instructions below you will find the
programming easy and straight forward.
ENTERING RESET OPTIONS
ProtoSound® is equipped with a few programmable features that are
accessed in the RESET state by moving the transformer throttle up and
down between full voltage and low voltage (6 to 8 volts) without shutting
the transformer off completely. Each time this is done you advance, one
feature at a time, through the available options. An air-release sound is
heard each time the throttle is advanced. In addition, there are special
sounds to tell you what RESET position you are in.
For example, if you want to select Feature 2, you put the engine in
RESET, and move the throttle up and down from full throttle to low two
times. After the second advance, you will hear two “clinks" indicating that
the computer is now in Feature 2. Advance the throttle again and you will
hear three “clinks" for Feature 3. Advance it two more times and you will
hear a “clank" indicating
that you are now in
Feature 5. Advance the
throttle two more times
and you will hear a
“clank" and two “clinks"
indicating Feature 7. ((5
throttle advancements = 1
clank) + (2 throttle
advancements = 2 clinks)). “Clank + “Clink" + “Clink" = Feature 7. You
can advance the throttle as quickly as you like (though you may not hear the
air-release sounds) and the computer will still remember the number of

times the throttle is advanced by playing back the number of “Clinks" and
“Clanks" to confirm the feature you’ve selected.
SETTING THE ENGINE VOLUME
Of all the sounds that come with each ProtoSound®-equipped locomotive,
the one most often turned down is that of the engine volume because it is
the one sound normally heard whenever the engine is running and is what
usually can become tiresome to the ear over prolonged running sessions.
The volume adjustment is controlled through RESET Feature 6.
To access the feature, advance the transformer throttle to put the engine in
RESET. Move the throttle up and down, as described on page 18, 6 times.
After you hear the “clank" and “clink" indicating that you are in Feature 6,
press the whistle button to select the engine volume level you desire.
Pushing the whistle button once will give you full volume, which is the
factory setting. Pushing the whistle button a second time will give you 50%
volume, pushing it a third time will give you 25% volume and pushing it a
fourth time will give you no sound. The microprocessor will immediately
play the sound level each time the whistle button is pushed so that you can
decide if it is acceptable. You can recycle through the four choices by
simply continuing to
press the whistle button.
Once you have decided
on the appropriate
volume level, turn the
transformer throttle off
and on again or press the
transformer direction switch to lock in your selection. The volume
adjustment will remain set at the level you have chosen until you change it
again. Regardless of the engine volume setting, the horn, bell, compressor
and Cab Chatter sounds will function normally. In fact because only the
engine volume is affected by selections in Feature 6, when you select 0
volume, you can still hear the horn, bell and Cab Chatter sounds when the
engine is running or in neutral.

PROGRAMMING FOR A SEPARATE BELL BUTTON
CONTROLLER
To operate ProtoSounds® with
a separate bell button controller,
like the Lionel® No. 5906 bell
button, you will need to wire up
the controller to your
transformer and track as shown
in Fig. 5. Once the button is
wired, ProtoSounds® comes
preprogrammed to allow you to
operate the bell by simply
pushing the bell button once.
To turn the bell off, push the
button again. If the bell doesn’t’t function when you press the button, you
may need to re-program ProtoSounds® to operate with a separate bell
button controller. To do this enter RESET and go to Feature 20. (See the
section Using RESET To Program ProtoSounds®on page 17.) Once in
Feature 20, press the
whistle button and wait
for the module to sound a
bell ding(s). Continue
pushing the whistle
button until the module
plays back two dings
(signifying that the
module has been
programmed for a bell button). Simply turn the throttle off and then on
again to “Lock-In" the new setting. To reset the computer to its original
factory (default) setting (separate bell button operation), repeat the above
procedure but keep pushing the whistle button until the computer only
responds with one bell ding.
PROGRAMMING FOR SQUEAKING BRAKE
OPERATION
ProtoSounds® can be programmed for squeaking brake operation in three
different manners; (1)Squeaking brakes can be activated by bell button
control, (2)they can be programmed for continuous operation subject to
throttle changes or (3)they can be programmed to be turned off. The default
setting is (2) Squeaking brakes are activated for full-time operation as
